Biodegradable polymeric endoluminal sealing process, apparatus and polymeric products for use therein

Abstract

A novel process for paving or sealing the interior surface of a tissue lumen by entering the interior of the tissue lumen and applying a polymer to the interior surface of the tissue lumen. This is accomplished using a catheter which delivers the polymer to the tissue lumen and causes it to conform to the interior surface of the lumen. The polymer can be delivered to the lumen as a monomer or prepolymer solution, or as an at least partially preformed layer on an expansile member.

What is claimed is:  
     
         1 . A catheter device for application of a polymeric coating to a tissue lumen comprising a flexible tubular body having proximal and distal ends, which tubular body defines a lumen divided into a plurality of sublumens, each sublumen extending from the proximal end of the tubular body toward the distal end of the tubular body and connecting to at least one aperture in the tubular body whereby each sublumen forms a conduit for fluid flow between at least one aperture in the tubular body and the proximal end of the tubular body, characterized in that at least one of said sublumens controls delivery of polymeric coating material to the tissue lumen.
